Professional Services by region (17)

Each region is a page of its own, holding only the professional services providers headquartered there. Greyed pills are below the 5-provider floor — published as a roster, without generated statistics.

Professional Services by country (27)

Country membership is matched on an exact country tag only — no headquarters signal — so these cells understate by construction and read lower than the region cuts above.
